I can’t seem to get a simple answer from Customer service in my allotted time to speak to them. (Lunch break)

 I just received both the above ordered as a bundle. Came with a sweet RCA cable and no way to connect to the 5! I think it should be a Y connector of sorts. Any recs? (Why did they not suggest one as an add on for a 998 dollar purchase is beyond me!!)

thanks!!
